How to make a bow with cardboard

The steps of making a bow out of cardboard are as follows:

Material preparation: some cardboard, glue or double-sided tape, scissors, art knife, rubber band.

1. Cut three rectangles of the same size.

2. Draw two narrow rectangles on two thirds of a rectangle and cut them off to form a T-shaped handle.

3. The first step is to take out a rectangle and dig out a rectangle in the middle to form a hollow cardboard.

4. Cut out two long and thin rectangular cardboard and stick them on the remaining rectangular cardboard in the first step, and the two long and thin rectangular pasting positions are lower on both sides respectively.

5. Stick the cardboard hollowed out in the second step on the cardboard in the fourth step, and stick two cardboard staggered up and down. The upper edge of the hollowed-out cardboard is aligned with the upper edges of the two cardboard strips. After pasting, according to the length of the cardboard strips on both sides, the upper and lower redundant cardboard strips are removed to form a small carton.

6. Insert the T-shaped handle in the first step into the paper box, and hang rubber bands on both sides to complete the main body of the slingshot.

7. You can draw some shapes you like on the remaining cardboard, cut them out and use them as bullets. Pull open the T-handle and put the bullets in the hollow part of the carton. Once you let go, the bullets will fly out.

8. The paper slingshot has been completed. See if your slingshot can eject a bullet! Hurry up and have a try with your friends to see whose "bullet" flies far.

The origin and classification of slingshots

origin

Slingshot became popular in 1970s and 1980s. Slingshot is a cold weapon or a game tool. Slingshot is generally composed of bow frame, rubber band and leather bag. It is usually a "ya" shape made of branches. Rubber bands are tied at both ends of the rubber band, and a piece of skin wrapped in a projectile is tied in the middle of the rubber band.

The strength of the slingshot depends on the tension and rebound speed of the rubber band. The greater the tension of the rubber band, the heavier the projectile that can be matched, and the faster the rebound speed of the rubber band, which can provide a larger initial velocity for the projectile. The heavier the projectile, the higher the muzzle velocity and the greater the power.

According to the launching mechanism, slingshots can be divided into bow slingshots and elastic slingshots. Bow slingshot has the most primitive bow slingshot and crossbow.

classify

Rubber-band slingshots can be divided into traditional slingshots and modern slingshots, and their division principles should be based entirely on the presence or absence of sights and wrist rest labor-saving devices. For example, wooden slingshots and steel wire slingshots without sight belong to traditional slingshots, and the so-called "traditional bow" with sight formed by cutting or casting metal wire should be strictly classified into the category of modern bows.

Because in the whole world, before the development of horizontal grip aiming in China, no one or product popularized the principle of horizontal grip aiming. The earliest horizontal aiming was Wind of the King, which initiated the application and promotion of horizontal aiming in slingshot products and was the originator of horizontal aiming slingshot.
